Enable background detection for adaptive quantizer control This commit enables a background detection approach for adaptive quantizer control. It combines the cyclic refresh pattern and the background information to determine the segment id for adaptive quantizer selection, prior to the non-RD mode decision process. It hence allows proper quantization information update for a more precise rate-distortion modeling in the non-RD mode decision. The compression performance of speed -5 for rtc set is improved by 2.5%, at no speed change. Change-Id: Ic3713e8ed9185b403b5b1679d19dabd57506d452
